What is Flow Tray used for?
Flow Tray is a runoff collection tray designed to keep your grow space cleaner and drier. It works with soil, coco, and hydroponics, and is compatible with fabric, plastic, and air-pruning pots, both indoors and outdoors.
How does Flow Tray manage runoff in run-to-waste systems?
Flow Tray collects excess feed and directs it away from the pot base. It works with or without plumbing and can connect to drain lines, buckets, or reservoirs. A slight slope improves drainage, but it functions well as a standalone catch tray too.
What sizes does Flow Tray come in, and what pots does it fit?
Flow Tray comes in two sizes: 15.5" for pots up to 50L, and 22" for pots up to 95L. Choose based on your pot size and tent footprint. Both sizes are built to handle heavy containers and messy runoff.
Does Flow Tray have adjustable legs?
Yes, Flow Tray features adjustable legs to help level your setup, lift pots off the ground for better airflow, and fit into tight grow spaces. It's ideal for grow tents and can be used individually or in multiples.
Can Flow Tray help prevent root rot and fungus gnats?
Yes—by keeping pots out of standing runoff and improving airflow around the base, Flow Tray reduces the risk of root-zone issues and makes your grow space less inviting to gnats.
What watering methods is Flow Tray compatible with?
Flow Tray works with hand-watering, drip irrigation, halos, rings, auto-feed systems, and even flushes. It catches runoff cleanly no matter your watering style and reduces floor mess.
Can I monitor fertigation runoff with Flow Tray?
Yes—Flow Tray makes it easy to measure runoff volume and collect samples for EC and pH testing. It helps you spot overwatering, underwatering, or salt buildup early on.
How do I clean and maintain Flow Tray?
Rinse and wipe it regularly, especially after each grow cycle. Prevent salt crust or algae buildup with occasional deep cleaning. If runoff smells, improve drainage and empty waste containers more often.
Does Flow Tray reduce humidity and protect my grow area?
Yes—by preventing puddles, Flow Tray helps stabilize humidity and protects nearby cables, pumps, and powerboards from water exposure. It's a big upgrade for grow room safety.
How do I set up Flow Tray for stability?
Place it on a level surface and adjust the legs evenly. For uneven tent floors, a rigid board can help. It’s built to hold heavy pots, and leaks are rare if tubing and fittings are secure.
What are common mistakes to avoid with Flow Tray?
The biggest mistake is letting runoff sit too long—always drain or empty promptly. Another is failing to level the tray, which can lead to pooling and bad smells. Keep it clean and drained for best results.
Is Flow Tray reusable and durable?
Yes—Flow Tray is designed for repeated use across multiple grows. It's safe with most nutrients and additives as long as you clean it regularly to avoid buildup or cross-contamination.
Is Flow Tray good for SCROG or commercial grows?
Absolutely. It’s a huge time-saver under SCROG nets and scales well for multi-pot or commercial setups. It helps reduce cleanup and eliminates the need for constant shop-vac use.
Will Flow Tray work with any pot design?
Yes—it’s built to accommodate most common pot bases, including fabric and air-pruning styles. For better flow, use risers if needed to prevent the pot from blocking drainage slots.
Is Flow Tray beginner-friendly and easy to set up?
Yes—it’s a plug-and-play system. Just adjust the legs, place your pot, and start collecting runoff. It helps beginners avoid mess, manage watering better, and keep their grow space neat.
